So sorry for your loss. I live in Florida and have to deal with the heat. I do have large pens for my birds that I planted trees in many years ago for shade. My coops are well ventilated. We get a lot of rain especially in the summer months so I built rain/shade tables for the birds to get under too and they do like to get under them. The only way to be 100% sure what your bird died from is a necropsy. There could be any number of reasons. Good luck...
So sorry for your Losses, best of luck.
